14 best fuel system cleaner additive

Fuel system cleaner additives are chemical compounds designed to improve the cleanliness and efficiency of an automotive engine's fuel system. These additives are typically mixed with gasoline or diesel fuel and work to remove deposits, varnish, and other contaminants that can accumulate in various components of the fuel system. Here's what you need to know about fuel system cleaner additives:

  1. Purpose: The primary purpose of fuel system cleaner additives is to maintain or restore the optimal performance of a vehicle's fuel system. Over time, deposits can accumulate on fuel injectors, intake valves, combustion chambers, and other critical parts of the fuel system. These deposits can hinder fuel atomization, combustion efficiency, and overall engine performance.

  2. Benefits: Using a fuel system cleaner additive can offer several advantages, including:

    • Improved fuel economy: By cleaning fuel injectors and other components, the additive helps maintain proper fuel atomization and combustion.
    • Enhanced engine power: Cleaner fuel systems can result in better throttle response and increased engine power.
    • Reduced emissions: Improved combustion efficiency can lead to lower levels of harmful emissions, such as carbon monoxide and hydrocarbons.
    • Prevention of engine knocking: Clean fuel injectors can help prevent engine knocking or pinging, which can occur due to poor fuel atomization.
  3. How It Works: Fuel system cleaner additives typically contain detergents and solvents that break down and dissolve carbon deposits and other contaminants. When added to the fuel tank and mixed with the fuel, these additives are carried through the fuel system as the engine runs. They clean deposits from fuel injectors, intake valves, and other critical parts.

  4. Usage Recommendations: The frequency of using fuel system cleaner additives can vary depending on the product and the level of contamination in the fuel system. It's often recommended to use these additives periodically, such as every 3,000 to 5,000 miles, to help maintain cleanliness. However, it's essential to follow the specific instructions provided on the product label or in the vehicle's owner's manual.

  5. Types of Fuel System Cleaner Additives: There are various brands and formulations of fuel system cleaner additives available on the market, each with its unique blend of cleaning agents. Some additives are designed for gasoline engines, while others are formulated for diesel engines. Additionally, some products may target specific issues, such as injector cleaning or combustion chamber cleaning.

  6. Preventative vs. Corrective Use: Fuel system cleaner additives can be used both preventatively and correctively. Preventative use helps maintain a clean fuel system, while corrective use is employed when a vehicle is experiencing symptoms of fuel system contamination, such as reduced performance or increased emissions.

  7. Professional Cleaning: In severe cases of fuel system contamination, it may be necessary to have a professional mechanic perform a more thorough cleaning using specialized equipment and solvents. This is typically reserved for situations where fuel system deposits are significantly affecting engine performance.

In conclusion, fuel system cleaner additives are a convenient and relatively inexpensive way to maintain the cleanliness and efficiency of an automotive engine's fuel system. Regular use, in accordance with product recommendations, can help optimize engine performance, fuel economy, and emissions.

User questions & answers

Question: Do people really use this every 3,000 miles? How often do you do it
Answer: Techron has a web site and a contact number to call. Unless someone has opened up the engine block and tested how this additive performs, they are just guessing. Granted, Techron may just be trying to sell you something that you do not need, or need every 3,000 miles.
Question: it's a real pain to open Techron bottle's seal. do you guys have any tips on opening it easily
Answer: Don't try to peel it off. Just pierce it through the center (not at the edge) with a sharp pointed blade, like one on a little Swiss Army keychain knife. Leave the slit alone and don't try to peel any of the seal off. If you just pierce it in the center and don't try to pull off or peel any pieces it will remain intact and tightly adhere to the bottle neck and thus continue to provide an effective seal when you close the cap.
Question: I found an old unopened bottle of the original concentrate, not the Plus. Probably 10 years old. Is it still OK to use
Answer: Yes, its fine to use. The ingredients don't go bad for maybe 20 plus years or more
Question: Is there any reason why after using this that I should also use Chevron's fuel injector cleaner or does this do the same thing
Answer: Both products contain the same cleaning additive (polyetheramine), the "fuel injector cleaner" just contains slightly less (and is usually slightly cheaper) than the "fuel system cleaner".

User questions & answers

Question: It's good to put it before fill up or after
Answer: Dump it in at the pump before filling up. That way the fuel rushing into the tank will mix it in rather than dumping it in after filling. Eventually it'll attain uniform mixture but dump then pump will mix it right away.
Question: I can run Sea Foam in the crankcase along with my oil at all times or just as a cleaner prior to changing the oil
Answer: It says right on the bottle, you can add it in the crankcase 100-300 miles right BEFORE oil change.
Question: how does it do in motor oil
Answer: I just used Sea Foam in my oil for the first time. I have a 50 year old car with its original, never-rebuilt motor. The lifters have been tapping for awhile so I thought it was worth a try. I added Sea Foam to the crankcase oil according to the directions (1.5 oz. per quart of oil). I let the motor run for about 15 minutes. The lifter noise went away almost immediately. Afterwards, I changed the oil as normal. When I drained the old oil, it was noticeably thinner due to the presence of the Sea Foam. I added new oil and filter, and the engine runs like a top now. No more noise. This stuff is great.
Question: This item (Sea Foam Motor Tune-Up) oil additives? Or fuel additives
Answer: seafoam is mainly a fuel system cleaner and it does work well. as for your oil, it acts as a cleaner also, targeting sticky valves, dirty port holes , dirty lifter issues etc

BG 245 Premium Diesel Fuel System Cleaner

BG

Based on 300 reviews Check latest price

Product description

BG 245 Premium Diesel Fuel System Cleaner removes and dissolves deposits from the entire diesel injection system, including fuel injectors and combustion chambers. Diesel fuel is notorious for its instability. Without adequate fuel stability to control deposit formation, diesels are extremely sensitive to fuel breakdown. This can increase deposit buildup, leading to heavy exhaust emissions and power loss. In newer high pressure common rail (HPCR) direct injection engines, high temperatures and pressures can cause diesel fuel to breakdown into carbon deposits more quickly. The result is poor performance and potential engine damage. Current diesel fuel system cleaners remove deposits from the injector tip but fail to reach inside the injector itself. BG 245 removes and dissolves deposits from the entire diesel injection system, including inside fuel injectors and combustion chambers. BG 245 is especially effective in removing heavy deposits inside the injectors of high temperature, HPCR fuel delivery systems. Plus, BG 245 contains a fuel lubricity agent and cetane improver for cold starts.

  • NEW FROM BG. NEW VERSION OF BG 244
  • Cleans entire diesel fuel injection system
  • Is especially effective in high pressure common rail engines
  • Removes hard deposits inside injectors
  • Improves cold start, lowers emissions, smoothes idle.

User questions & answers

Question: Lift pump? Will it have the same effect even though I have a Airdogg lift pump installed
Answer: Techron has a web site and a contact number to call. Unless someone has opened up the engine block and tested how this additive performs, they are just guessing. Granted, Techron may just be trying to sell you something that you do not need, or need every 3,000 miles.
Question: does this product have any negative impacts on diesel engines using DEF
Answer: Don't try to peel it off. Just pierce it through the center (not at the edge) with a sharp pointed blade, like one on a little Swiss Army keychain knife. Leave the slit alone and don't try to peel any of the seal off. If you just pierce it in the center and don't try to pull off or peel any pieces it will remain intact and tightly adhere to the bottle neck and thus continue to provide an effective seal when you close the cap.

User questions & answers

Question: Here's a question: What is the difference between a fuel injector cleaner and a fuel system cleaner? Don't they all go through the same paths
Answer: This is also why it is a good idea to follow this treatment with the fuel system cleaner so the injector cleaner is flushed from the fuel system.
Question: do I use this every 3 months
Answer: So many factors really matter. For instance if you live in a cold place and deal with stop and go, you will most likely have more carbon build up. Also if you only do short trips. I would usually add one bottle ever 3000 miles or every oil change for my Rav4 at 5000 miles.
Question: What's the difference between this and lm valve clean? ty
Answer: Jectron is designed for fuel injection system cleaning, smoother idle, improved throttle response. Valve Clean is specifically engineered for removing harmful deposits on valves and in the combustion chamber. It will also have beneficial intake and injection system cleaning effects; but its primary duty is valve deposit reduction.

Question: Could someone kindly share their experience on how well this product works with automobile carburetors? Thanks
Answer: Absolutely!
Question: Can I use it for mowers? Will this clean the carburetor in a 25-yr old Craftsman 4.5 hp lawn mower
Answer: I heard that RedLine is the best as well....but Gumout Regain works well with my vehicle....and is a little less costly.
Question: Can I use it for mowers
Answer: If you want to be safe, run all that fuel out before the test. That way you will get all the cleaning benefit. Honestly, I do not think the chemicals will change the test if that was your question. The Cat converter will burn most everything.
Question: Is this safe for use in diesel tractor engines
Answer: When I was checking into options the details were on the Gumout website. This had the highest percentage. I used it in a Hyundai Accent with 50,000 miles that never had cleaner before. I noticed an immediate improvement in the responsiveness and got back a couple MPG.
